## Abstract A mathematical analysis is presented of molecular integrals of relativistic interactions in molecules. The integrals are based on Gaussianβtype orbitals and include those arising from variation of electron mass with velocity, oneβelectron Fermi contact interaction, electron spinβsameβor
## Abstract An analytical derivation of multicenter and multiparticle integrals for explicitly correlated Cartesian Gaussianβtype cluster functions is demonstrated. The evaluation method is based on the application of raising operators that transform spherical cluster Gaussian functions into Cartes
